Kino Preferences
Capture
- Base File Name
- Enter the path where you want to store captured video
followed by a file name stem. Do not add the extension.
Kino generates a sequence number and optionally a timestamp
that it appends to the stem file name. It also generates
the file extension, currently only .avi.
- File Type
- Currently, Kino only supports DV AVI file formats. You can
choose between standard DV1 or DV2 formats. DV2 is more compatible
with other applications because it creates a separate interleaved
audio stream. However, if you are only capturing for Kino use or
for another program that supports DV1, then choose it because DV
natively interleaves audio with the video and the audio stream
in DV2 is wasteful. MPlayer and Avifile only playback DV2 AVI.
Current versions of Windows DirectShow do support DV1, but
Windows application support for DV1 is inconsistent.
- Auto Split Files
- Generate a new file whenever Kino detects a new scene
while capturing video.
- Put Timestamp In File Name
- If enabled, during capture, Kino appends a date and time to the base
file name specified above.
- Frames per File
- Set the maximum number of frames a single AVI is to contain. While
Kino has recently added support for reading large files, it
does not support writing large files. The default is 7000 frames,
which should be safe for PAL DV2 files. An NTSC DV1 file can hold
9000 frames.
- Write Every n Frame
- This is time-lapse record function. If entered, Kino skips
n frames between capturing a single frame and adding it to the AVI.
- Max File Size
- Not yet implemented.
IEEE 1394
- IEEE 1394 Interface
- This provides support for multiple IEEE 1394 host adapters,
NOT the individual ports on a single adapter. Nothing needs to
be done to address a port on a single adapater, as 1394
automatically takes care of this. This is a zero-based number.
- IEEE 1394 Channel
- This provides support for selecting an isochronous channel for
capture and export. The default is 63 because that is the broadcast
channel. All other channels are for point-to-point communication.
Only advanced users would ever need this.
- VCR (AV/C) Control
- Kino detects all cameras on the bus that support the AV/C command
set. Select one from the list. It attempts to read the name of the
device from its Configuration ROM, but not all devices implement it.
If the name is not readable, then the numeric node is used. Most users
only have one AV/C device connected anyway. You do not need a camera
supporting AV/C to capture video! It is only used to control the
tape transport mechansim.
- DV Export/Timing
- These two timing entry fields let you tweak the parameters of the
DV export algorithm to achieve successful results. A value of
0 for either field selects its built-in default, which has been
deemed compatible for most users based upon current feedback.
However, if you need to adjust them, then it helps to know the
built-in values to use as a starting point for experimentation:
Setting |
PAL |
NTSC |
Increment |
1 |
2436 |
Threshold |
16 |
38400 |
- DV Export/SYT Offset
- video1394 must generate a timestamp in DV transmission
stream that must be a fairly precise offset of the bus'
master cycle timer. This can vary on systems due to latency
or device compatibility. Values between 18000 and 20000 seem
to work for most users.
Display
- Display Method
- GDK: very compatible with X servers and the X Windows
client/server architecture. Not very fast.
Does not maintain frame aspect ratio.
XVideo (Xv): requires XFree86 4.x and supporting hardware
and X server. Run 'xvinfo' from the shell to get information about
support on your system. Very fast and Kino maintains both frame and
pixel-accurate aspect ratio. You can not take a screen capture of
the video preview in this mode. XVideo is similar to Microsoft
DirectDraw.
Reduce Xv: Similar to XVideo above with the same advantages
and disadvantages. This variation, however, uses half of the data
bandwidth that is needed for compatibility on some X servers and
hardware. The reduction in data bandwidth does invoke a scaling
CPU overhead thereby affecting performance.
- Enable preview during capture
- To reduce the chance of dropped frames during video capture
to disk, disable this option. If you have a fast enough system,
you can turn this om and get a live preview of the video being
captured.
- Drop video frames as needed
- When enabled, Kino uses sophisticated algorithms and threads
to sacrifice the video frame rate in order to provide better
audio quality of play back and to provide an overall playback
rate that is consistent and true with time. Basically, only
disable this if you are interested in seeing if you machine
is fast enough to decode DV in realtime. If you machine is not
fast enough, then your will hear audio clicks and gaps.
- DV decode quality
- You can adjust the quality of the DV decoder to reduce
the processing overhead for increased playback performance.
This does not affect the quality of DV exported over
IEEE 1394 back into your camera.
Audio
You can enable or disable audio and set the OSS device file
to use for your machine. Kino only supports OSS at this time.
If you are running a sound server in your desktop environment
such as esd for GNOME, or aRts for KDE, then Kino cannot open
the sound device unless your driver explicitly supports it.
The SoundBlaster Live series cards and driver support
multiple opens.
Jog/Shuttle
Enable this if you have a Contour Shuttle Pro or Sony USB
Jog/Shuttle controller. See the README_jogshuttle to build
the kernel module and its dependent modules.
Other
- Disable Key Repeat
- If you find that your keystrokes are buffering and you
inadvertently have to wait for Kino to process all of them,
then you might enable this option. If enabled, Kino only operates
on the oldest event in the queue and discards all pending events.
On the other hand, enabling this option may require you
to use the keys more slowly in order for Kino to receive the
ones you do intend it to process.
- Enable time code display on startup
- By default the video clip timestamp and timecode display
is turned off for performance reasons. You can click the
timecode field labels in the main window to turn them on,
but Kino does not automatically remember that. Enable this
option to make Kino always start with the timecode display
active.
